What version of Photoshop do you own? Mac or Windows?
What model camera?
- Which version of PS are you using?
- Update your PS and Camera raw will be updated as well, Camera raw is a part of PS it is not a different application.
i have PS 5.1
Relating to what gener7 said, can you not open RAWs from a camera or is Camera Raw itself not working?
We need to know what version of Photoshop and what OS you are running so we can get you to the correct downloads and instructions for your Mac or PC. You can get that information in the first two lines of Help > System Info in Photoshop. I need to know what model of camera you are getting your raws from so I'll know if Camera Raw can open it or not. Open a jpeg in Camera Raw and tell us what version you see in the title bar.
"5.1" refers to CS 5.1 which is pretty old. Camera Raw won't go past 6.7 leaving a lot of new cameras out. You would have to convert those raws to DNG format and then open it in that earlier version of Camera Raw.
But as said earlier, we need information to get you the correct answer.
